Is Conference Room Air Making Us Dumber?

I monitored the CO2 in my bedroom every second for three months and I found results similar to you. If I was sitting right next to the sensor in the evening it would go up to about 1900 ppm. Cracking open the window for an hour or so eventually brought things down to the 500ppm range.

What was interesting is how fast the ppm increases when someone enters the room. I would plot the data and see a blip on the graph when I entered. It was within seconds of entering.

I noticed the same when I am sitting near the sensor. I'm thinking though that it is partially due to me essentially breathing onto the sensor and the sensor dynamics having an averaging function so that I'm not sure what the sensor reports and what I breathe in are the same. Repositioning the sensor so it wasn't in the "line of sight" of my breath changed the readings significantly.

Here's a plot. The peaks are when I was in my apartment. The gap in the middle of February was when I went on vacation.

That is really cool. Thanks for sharing, I love it when people collect data.
